GPC-QC is a compact high-temperature GPC instrument for quality control in polyolefin manufacturing lines. The instrument has a simple and reliable approach based on the recently developed QC platform, to provide robust and precise Molar Mass Distribution for process control. Thus, fulfilling the need in the industry of adding the complete curve to the routine process control tools in the manufacturing plants.
Traditionally, some bulk physical parameters, such as melt flow index (MFI) and density, have been used in the industry for this purpose despite their limited scope. However, for complex multiple reactor products, having multimodal MMD, the limitation of such approach becomes a critical issue.
GPC-QC delivers the complete Molar Mass Distribution for one sample through a simplified workflow, while keeping full automation of sample preparation and analysis -free of manual solvent handling throughout the entire process, which takes 30 minutes including dissolution.
The IR detection implemented in the instrument through Polymer Char's integrated IR4 or IR5 MCT detectors, is highly stable, contributing to the overall reliability while at the same time, providing chemical composition information, which is key for controlling production of heterogeneous resins.
Moreover, for a truly complete analysis, the instrument can measure intrinsic viscosity by means of a built-in dual capillary viscometer that can be incorporated optionally.
Important applications for GPC-QC are:
